I build backend features in Nest.js and Node.js, working through JIRA tickets in fast-paced teams at Aventage Labs Pvt Ltd. I’ve integrated cache/ORM persistence layers, implemented event-driven business logic, and fixed data-integrity issues around nested entity updates.

On Connect, I also enforced API-level changes end to end while migrating tenant configuration from static to database, and I verified correctness through targeted backend integration testing. I strengthened request validation using custom wrapper validators and resolved query response ordering inconsistencies at the database level.

For Advanced Business Application, I closed an ABAC authorization gap by enforcing immediate access revocation at the guard level when tokens outlived deactivated users. I worked across Visit Management and Product Management query APIs in daily Agile sprints with Frontend, Backend, and QA collaborators.

Before that, at Dipro IT Pvt Ltd, I contributed to a Flask API and improved authentication with JWT and OAuth. I also used RabbitMQ for message queuing, and I supported backend service development alongside a mobile client in an Agile delivery flow.
